A swimming pool structure must safely retain water and resist external loads (soil, surcharge, thermal, seismic). Typical structural elements: vertical walls, base slab, edge beams, and supporting foundations. Key design considerations: hydrostatic pressure, earth pressure, uplift, buoyancy, thermal/hydraulic effects, crack control, durability in a chlorinated environment, and constructability.
Concrete Cover: Due to constant exposure to moisture and chemicals, a higher "concrete cover" (the distance between steel and the concrete surface) is required—typically —to prevent rebar corrosion. structural design of swimming pool pdf
Steel Reinforcement: A "cage" of rebar is essential to provide tensile strength to the concrete. This includes horizontal and vertical bars spaced according to the depth and length of the pool. Structural Design of Swimming Pools — Short Report
The coping is a critical component of the swimming pool design, meeting the pool shell and decking. The following design considerations must be taken into account: Walls: design as cantilever or propped retaining walls;
| Load Type | Description | Typical Value (Residential) | |-----------|-------------|------------------------------| | Dead Load | Self-weight of concrete, plaster, tiles | Calculated from density (24 kN/m³) | | Water Pressure | Lateral and uplift | 9.81 kN/m² per meter depth | | Earth Pressure | Soil against walls (active/pressure) | Depends on soil class (γ_soil ≈ 18 kN/m³) | | Live Load | People walking around deck | 2.5 – 5 kN/m² | | Uplift (Buoyancy) | Water table above pool invert | Most critical for empty pools |
